Emma may be correct because the difference between the succeding term and the preceeding term are increasing in a sequential order from 1, 2, 3, 4, ....
In Mathematics and Geometry, a sequence is a series of real and natural numbers in which each term or list of elements are ordered in a particular order and repetitions are allowed.
Based on the information provided about the pattern, we can logically deduce that the difference between the succeding term and the preceeding term are increasing in a sequential order from 1, 2, 3, 4, ....;
Difference = 2 - 1 = 1
Difference = 4 - 2 = 2
Difference = 7 - 4 = 3
Difference = 11 - 7 = 4
